I use this tool to help manage my Proxmox server, and I could never go back

Compared to OmniOS and TrueNAS Scale, Proxmox has a fairly straightforward UI, and you can get accustomed to its quirks after reading its massive documentation. That said, Proxmox tends to hide certain advanced settings behind a barrage of menus, which can be annoying to navigate when you’re just starting out. Likewise, certain features can only be enabled after executing a stream of commands inside your PVE node’s Shell interface.
